Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric windshields, specifically to a gear meshing and clamping device and an electric windshield. Background Technology
[0002] Electric windshields have a wide range of applications, not only for keeping warm in winter, but also for wind protection in spring and autumn. They can significantly reduce the direct impact of wind, reduce wind resistance when riding, make riding more stable and comfortable, and provide extra warmth.
[0003] However, during cycling, wind pressure causes the rack in the lifting module, which connects to the windshield, to experience reciprocating thrust. This leads to deformation at the connection between the gear and the slide, resulting in a large gap between the rack and the gear, which inevitably affects the windshield's lifting operation. Therefore, a gear meshing and clamping device and an electric windshield are needed to improve the rack's stability and, when a large gap occurs between the rack and the gear, to reduce the gap through adjustment, thus avoiding any impact on the lifting operation. Utility Model Content
[0004] The purpose of this utility model is to provide a gear meshing and clamping device and an electric windshield.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] A gear meshing clamping device and an electric windshield are provided for pressing the rack in the electric windshield toward the gear. The device includes a support plate fixedly mounted on a slide, and the end of the support plate is provided with a presser for pressing the rack toward the gear.
[0007] Furthermore, the contact point between the pressure reducer and the rack is located on the upper half of the rack, away from the slide.
[0008] Furthermore, the presser is a screw, and the support plate has a threaded hole that engages with the screw.
[0009] Furthermore, the support plate is connected to the slide block by multiple hexagonal screws, and the top of the slide block has screw holes for hexagonal bolt installation.
[0010] Furthermore, the support plate has a Z-shaped structure.
[0011] Furthermore, the electric windshield is equipped with the aforementioned gear meshing and clamping device.
[0012] The beneficial effects of this utility model are as follows: The gear meshing clamping device and electric windshield extend the lower pressure unit to the top of the rack through the support plate, and when the rack becomes loose, the rack can be adjusted towards the gear to reduce the gap between the two, improve the meshing stability between the rack and the gear, and avoid affecting the lifting operation.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0019] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.
[0020] Reference Figures 1 to 3 The gear meshing clamping device and electric windshield shown are used to press the rack 1 in the electric windshield towards the gear 2. It includes a support plate 4 fixedly mounted on a slide 3, with a pressure device 5 at the end of the support plate 4 for pressing the rack 1 towards the gear 2. Since the rack 1 is fixedly connected to the slide 3, the pressure device 5 is connected to the slide 3 via the support plate 4. When the slide 3 moves, the pressure device 5 moves with it, ensuring that the support position of the pressure device 5 on the rack 1 remains constant. Long-term riding causes the rack 1 to frequently move along... Figure 1 After the arrow direction is swung back and forth, the connection between rack 1 and slide 3 will become loose, and eventually a large gap will be generated between rack 1 and gear 2. It is necessary to rotate and push down by pressing down 5 to make rack 1 move toward gear 2 so that the windshield lifting function can still be used stably.
[0021] The contact point between the pressure reducer 5 and the rack 1 is located on the upper half of the rack 1, away from the slide block 3. This upper contact ensures sufficient clearance between the rotational position of the rack 1 and the contact point of the pressure reducer 5, guaranteeing stable support for the rack 1.
[0022] The pressure device 5 is a screw, and the support plate 4 has a threaded hole for engaging with the screw. The pressure device 5 is not limited to a screw; it can be any structure that allows for position adjustment on the support plate 4. For example, a sliding column with a limit switch.
[0023] The support plate 4 is connected to the slide block 3 by multiple hexagonal screws, and the top of the slide block 3 has screw holes for hexagonal bolt installation. The support plate 4 and the slide block 3 are fixedly connected by hexagonal bolts.
[0024] The support plate 4 has a Z-shaped structure, which allows the pressure plate 5 to extend directly above the rack 1.
[0025] The electric windshield is equipped with the aforementioned gear meshing and clamping device. This device facilitates user adjustment and maintenance, extending the windshield's service life.
[0026] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
